My invention relates to cigarettev lighters and particularly to pocketlighters of the pyrophoric A particular object of the invention is toprovide a lighter formed of two sections which, when they are pulledapart cause operation of the lighting mechanism to ignite a wick. Aspecial object of theinvention in a lighter of this type is to limit therelative sliding movement between the parts 1,0 so that when they arepulled apart a. certain distance no further motion is possible, This isan important feature inasmuch as where the parts are freely` separablethey are likely to be pulled apart so rapidly, in imparting the motionnecessary to cause the lighting mechanism to operate,

that any flame which is formed will be extiniuished by the motion of thelighter through the r. A further object of the invention is to provide alighter vof' this type in which the sections, movenot biased in any Wayeither towards or from each other, and are freely slidable through alimited range with respect to each other except forl the elements whichoperate the lighting mechanism. Still a further feature of the inventionresides in the fact that the lighting mechanism itself is utilized forresiliently holding the lighter in closed, inoperative position. o 0 yAfurther object of the invention is theproviv fuel chamber of the lighter-is filled at a point adjacent the wick, this point being, however,concealed and covered when the lighter Ais in closed position. Thisprevents the soiling of the clothes of the user by any fuel which mightpossibly leak out through the lling opening.'

Further objects and'advantages of the invention will appear more fullyfrom the following description particularly when takenin conjunctionwith the accompanying drawing which forms a part thereof. Inth'edrawlng: Fig. 1 is a side elevation showing a lighter acctziordingto the invention in open operative posion.

Fig. 2 is a crossl section through the same in closed position. 'Y

Fig. 3 is a cross section on the-line 3-3 of Fig. 2.

'I'he lighter comprises two sections A and B. The lower section B orbody ofthe lighter comprises a shell or framework 2 lwhich is open atthe bottom and is closed by a cap or shell 4. The 5;, inside of theshell 2 thus forms a fuel chamber 6.

ment of which causes operation of the lighter, are

sion of a novel filling arrangement, in which the The shell 4 may besecured on the frame 2 by means of a screw 8. 'I'he frame2 has an upwardextension I0 forming a part of the fuel chamber and holding in its top atube I2 in which is arranged a wick I4. This wick is preferably formedof a rigid, porous material, such as meerschaum. The wick I4 thusextends into and receives fuel from the fuel chamber. 'Ihe frame 2 alsoincludes at its other side an upward extension I6 which extends abovethe wick I4 and includes an upper continuous ring or frame section I8forming the top of the frame l2. This leaves a space 20 between the ringI8 and the extension I0' to permit access of air to the wick and toallow the user to bring his cigarette up to the wickA to be lighted.There is also provided between the upward extension I6 and extension I0and the member I8 a. vertical slot 22 the purpose of which will beexplained below.

'I'he upper section A includes a cover or a shell 24 adaptedv to slideover the upper part of the 20 frame 2 until it engages the upper edge ofthe shell 4. The arrangement then presents the appearance of a closedcasing. Inside of this shell 24 is mounted a snuffer tube 26 which, whenthe cover or shell 24 slides downwardly, covers the wick so as toextinguish the flame and prevent the evaporation of fuel from the wick.

There is also provided on the cover an inwardly extending tube 28. Thistube is closed at its upper end by a screw threaded plug 30 and enclosesa coil spring 32. 'I'he tube 28 acts both as a flint holding tube and asa support for 'the lighting mechanism. At the lower end of the tube 28is arranged a frame work 34 which sup- 35 ports a shaft 36 on which ismounted a flint wheel 38 in engagement with a flint 40 arranged in thebottom of the tube 28. Likewise mounted on the shaft 86 is an operatingpawl member 42 having a tongue 44 adapted to engage with ratchet 40teeth 46 on the side face of the flint wheel 88. It is evident that whenthis member turns in one direction (counter-clockwise, Fig. 2) it willimpart motion to the flint while upon turning in the other direction itwill move freely with re- 45 spect thereto. A spring such as a coilspring 48 of the element 42. This tongue is so arranged' that uponupward movement of the shell 24 it' will engage the hook 54 and causethe element 42 to turn in a clockwise direction against the action ofthe spring d8. When the cover or shell 2li reaches a certain 4pointinits travel, the inclination of the surface of the Yhook 5d will causeit to slide over and displace the end of the resilient.

member 5d, and then the member d2 will turn rapidly under the action ofthe spring 48,'thereby rotating'the int wheel to throw sparks on to thewick.

When the lighter is moving backward towards closed position the element42 slides easily over the resilient member 5G' back to the positionshown in Fig. 2.

' In order to limit relative sliding movement between the two sectionsof the lighter, I provide a pin 60 which is engaged andsecured in theopposed side walls of the shell 2li, and which passes through the slot22. It is evident that this pin will limit the relative movement of thetwo parts of the lighter betweenv the positions shown in Fig. 1 and inFig. 2.

In order to ll the lighter,I I provide a screw 62 arranged in the upwardextension i@ of the frame, in an aperture which communicates with thefuel chamber at a point near the wick. This screw is so located thatwhen the lighter is in closed position it is covered by the upperportion 2d. 4

If the cotton which lls the fuel chamber S is to beremoved for anyreason, it is only necessary to take out the screw 8 and the shell maythen be slid off the frame 2.

It will be noted that there is no mechanism biasing the lighter eitherto closed or open position, so that the motion is entirely controlled bythe user. However, when the lighter is in the closed position as shownin Fig. 2, the lighting mechanism itself holds the lighter againstaccidental opening since such opening involves a compression of thespring $8.

While I have described herein one embodiment of my invention I wish itto be understood that I do not intend to limit myself thereby exceptwithin the scope of the appended claims.
